EXHAUST CONTROL DEVICE FOR ENGINE

摘要

An exhaust control device for engine configures an exhaust system by joining exhaust pipes at a collecting pipe. The exhaust pipes are coupled to a plurality of respective cylinders. At least two types of exhaust valves are configured to perform an exhaust control at different parts in the exhaust system. The exhaust control device for engine includes first exhaust valves, a second exhaust valve, and an actuator. The first exhaust valves are mounted to a plurality of communicating pipes and communicating the predetermined exhaust pipes. The second exhaust valve is mounted to the collecting pipe. The actuator is configured to drive to open and close the second exhaust valve. The first exhaust valves are configured to be driven to open and close corresponding to an actuating region of the second exhaust valve.
